IMPRVEMENTIN APPARATUS FoR FEEmNG BLAST-FURNAcEs. 4

Specification forming part of LettersPatent No. 115,305, dated May 30, 1871.

To all whom it may concern:

" Be it known that I, LEVEN S. GooDRIcE, of

Waverly, in the county of Humphreys and State of Tennessee, have invented a new and useful Improvement in Blast-Furnaces; and I do hereby declare that the following is a full,

" clear, and'exact description thereof, which will enable others skilledin the art to make and use the same, reference being had to the accompanying drawing forming part of this specifb cation. y

This invention relates to improvements in blastLfurnaces; and it consists in an improved valve arrangement in the throat of the furnace, having forits obj ect'toenable me to distribute the coal, ore, and fluxes more evenly than has been heretofore done.

Figure l is a sectional elevation through the throat of a furnace anjdmy improved valve apparatus, and Fig.2 is a section of the furnace and side elevation of the valve apparatus.

Similar letters of reference indicate corresponding parts.

DI) represent the throat of furnace or top of `iii-wall, upon which is placed.my apparatus Vfor charging. i A A and A Al is a V-shaped circular shell, consisting of two conical, bottomless,cupshapedvessels,joinedatthesmallest ends, formed of anysuitable material, either in one or more pieces, and of such dimensions as may be desired to t the throat or top of the furnace operated up.0n," as shown in the drawfing.` `1B B2 `is a short cylinder, having a ared top, B B, to form a seat for` the coneO; and attached to B B isaiange, BX'BX, which closes as a valve against the under surface of 'A A. This tubular valve apparatus B B1 B2 is to be provided with any suitable apparatus forbeing lowered and `raised at will. C and C represent a valve 4formed by joining two cones at their bases.` FTF are guide-rods to j regulate the position of B B in .its movements.

` The dotted lines K K represent the cone-valve from the center.

I propose, .in using my distributer, to conlvey the charges in the usual cylindrical box with a valvular button overhead, where it discharges and falls into the hopper A A', irst the coal, then the ore or ilux, whereby, in descending into the hopper, it is .equally distribute'd around the cone C. Now, if the charge is desiredto be placed in the center of the stack, the cone Gis raised by suitable meanssay' a chain, J-and the charge descends. by `its gravity through the cylinder B2 B2, and in its descent the coal,ore, and ux are completely intermixed, forming a conical-shaped elevation of the stock at the center of the furnace. Now, in order to bring the surface of stock level Within the furnace-stack, I charge the hopper Al Al as before; but instead of raising the cone C, I now lower the entire valve apparatus B Bl B2 and cones C C so as to form an annular opening all around the same, through which the charge descends, thus bringing up the surface next the in-wall even with Vthe center. Thus, by alternating the charges as designated, a perfect distribution of the stock is secured and a greater amount of ore placed directlyv in contact with the carbon.

E represents the pipe for conducting the gas from the head of the stack to heating-stove or boiler, in which I place a valve to enable the manager to regulate the pressure within the stack at will. To enable the manager at all -times to know the exact pressure within the stack I place a large safety-valve, S S, at the top of the stack, with graduated lever and weights, by which he is enabled to ascertain the precise pressure he is working, and by changing the valve E he can increase or diminish the same at his pleasure.

Having thus described my invention, I claim as'new and desire to secure by Letters Patentv The combination, with the top wall D of a blast-furnace, of the top A A', the valve-tube B B1 B?, and the double conical plug C C', all substantially as specified.
